How this hook works

Pool guard

A very small hook whose only job is to make sure pools with it can only be created by one launch platform’s factory. It doesn’t touch trades, fees or liquidity.

Only the factory can create pools
When someone tries to create a pool with this hook, it checks who is asking. Anyone except the launch platform’s factory is refused, so nobody can set up a fake copy of a project’s pool with it.
The code that does this (beforeInitialize):
```
function beforeInitialize(address sender, PoolKey calldata, uint160) external view returns (bytes4) {
    if (msg.sender != address(poolManager) || sender != factory) revert NotFactoryInitialization();
    return IHooks.beforeInitialize.selector;
}
```
Nothing else changes
It runs only once, when the pool is created. After that, trades, fees and liquidity work exactly like a normal Uniswap pool, and nobody can take a cut.

Who controls it: Nobody can change it: the factory is fixed when the hook is deployed and there are no admin settings. The code itself can’t be changed.

Based on the hook’s published code.

Contract

✓Code is fixedNo proxy, so the code that runs today is the code that runs tomorrow.

✓No admin key foundIt has no owner wallet, so the hook developer has no single key to change its rules (as far as the standard check goes).

✓Source code publishedThe code on the block explorer matches what's deployed (contract: PoolInitializationGuard).

Pools

✓Pools trade in Uniswap’s appIt doesn’t touch swaps, so Uniswap’s app routes its pools automatically.

✓Won’t reject swapsNo beforeSwap, so trades always reach the pool’s curve.

✓Doesn’t touch swap amountsTraders get exactly what the pool’s curve and fee give.

Track record2 to review

!Not in Uniswap’s hook registryNot listed by Uniswap Labs, so nobody outside the hook developer has looked at it. Most abandoned and malicious hooks are unlisted.

!Brand newIts first pool was created less than a day ago, so it has no track record. Prefer proven hooks for a real launch.

?No audit linkedNothing in the registry. Ask the hook developer for one or review the source yourself.

What it can do

Runs at pool creation

It runs when a pool is created, often to lock in that pool’s settings.

Hook history

This hook has been quiet, so its past history hasn’t been read yet. New activity shows up here as it happens.

Counted from token transfers in and out of the hook. Its published code records no actions of its own. Still reading older history, so totals will grow.
